Day of the Dead Shout/Scream Factory 4K UHD Audio Removal, Replace and Remux

[Bluray-UHD_NAS_Guy]

This project is being done to combine the superior 4K video from the 2026 Shout Factory UHD with the corrected lossless audio from the 2018 Umbrella Australian Blu-ray.

The Shout release contains known audio problems, including altered/redubbed dialogue, a problematic Atmos mix and a 2.0 dual-mono track that is not the proper original mono presentation. The Umbrella release provides corrected DTS-HD MA 5.1 and 2.0 tracks with the original dialogue intact.

Because both releases run at 23.976 fps, the Umbrella audio can be synchronized to the Shout 4K video with a simple +1001 ms delay, without stretching, resampling or re-encoding. The goal is a movie-only remux that preserves Shout’s 4K picture while restoring the preferred audio presentations.

You will also need a standalone disc decrypter, not MakeMKV (although MakeMKV use "MAY" be possible to decrypt files to a folder then use tsMuxeR), and a UHD-friendly optical drive capable of reading the disc, such as a compatible modified OmniDrive, to extract the source files for this project.

Instructions:

Day of the Dead (1985) Custom 4K Remux

Shout Factory 2026 4K UHD Video + Umbrella 2018 Australian DTS-HD MA Audio

This procedure creates a movie-only custom remux using the video from the 2026 Shout Factory 4K UHD with the preferred DTS-HD Master Audio tracks from the Day of the Dead - Umbrella 2018 Australian Blu-Ray & DVD Release.

No video or audio re-encoding is required.

Important Frame Rate Information

Both releases use the same feature frame rate:

Shout Factory 2026 4K UHD: 23.976 fps

Umbrella 2018 Australian Blu-ray: 23.976 fps

They are NOT 24.000 fps.

Because both releases run at 23.976 fps, the Umbrella audio does NOT require stretching, resampling or frame-rate conversion to match the Shout 4K video.

Only the fixed +1001 ms timing offset is required.

You can confirm the frame rate of both sources with MediaInfo before beginning.

Shout 4K Source File

Use the largest feature .m2ts file on the Shout Factory 4K UHD as the video source.

Do NOT use the .mpls playlist for this procedure.

Verify that the large .m2ts file contains the complete movie before continuing.

This process does NOT reauthor the original Shout Factory UHD Disc structure.

You will NOT retain:

Original Shout menus

Original disc navigation

Extras not specifically included

Original commercial disc structure

The result will be a movie-only presentation containing only the video and audio streams you select.

Procedure

Open tsMuxeR.

Click Add and load the largest feature .m2ts file from the Shout Factory 2026 4K UHD.

Add the two extracted audio files from the Umbrella 2018 Australian Blu-ray:

DTS-HD MA 5.1, Stream 4352

DTS-HD MA 2.0, Stream 4353

Select the Umbrella DTS-HD MA 5.1 track and set:

Timeshift / Delay: +1001 ms

Select the Umbrella DTS-HD MA 2.0 track and set:

Timeshift / Delay: +1001 ms

Remove or uncheck the following Shout audio tracks:

Dolby Atmos / TrueHD

Shout DTS-HD MA 5.1

Shout 2.0 dual-mono track

Keep the Shout LaserDisc-derived DTS-HD MA 2.0 stereo track.

This should be the last main DTS-HD MA audio track in the Shout stream list.

Leave this track at:

0 ms

Keep any commentary tracks or subtitle tracks you want included.

Before muxing, your selected streams should be:

Shout Factory 4K HEVC video, 23.976 fps

Umbrella DTS-HD MA 5.1, +1001 ms

Umbrella DTS-HD MA 2.0, +1001 ms

Shout LaserDisc-derived DTS-HD MA 2.0, 0 ms

Any desired commentary tracks and subtitles

Output

Select the desired tsMuxeR output:

M2TS for a single movie-only transport-stream file

ISO for a movie-only disc image

Blu-ray folder for a movie-only Blu-ray structure suitable for compatible playback, burning or further authoring

None of these options will restore the original Shout menus, extras or commercial disc navigation.

The ISO and Blu-ray folder options are newly authored movie-only structures, not recreations of the original UHD.

Example filename:

Day of the Dead (Shout 4K, Umbrella DTS, No Atmos) [4K].m2ts

Verification

After muxing, verify both imported Umbrella tracks.

Because both the Shout 4K and Umbrella Blu-ray are 23.976 fps, synchronization should remain constant throughout the movie using the fixed +1001 ms offset.

Check synchronization:

Near the beginning

Around the middle

Near the end

You can also use the known dialogue differences below to confirm that the correct Umbrella audio is playing.

Est. UHD Time

Correct Umbrella / original audio

Incorrect Shout audio

9:16

Original "It's crazy" delivery

Redubbed voice

9:36

Flyboy says "s**t"

Says "right"

58:52

Complete Steel gunshot effect

Gunshot is truncated

61:38

Original Steel line reading

Alternate redubbed reading

71:25

Sarah says "Oh Jesus"

Says "I can't look"

80:36

Steel says "Jesus"

Says "stuck"

The quickest verification point is approximately 9:36.

With either Umbrella DTS-HD MA track selected, Flyboy should say:

"s**t"

If you hear:

"right"

you are listening to one of the altered Shout audio tracks rather than the corrected Umbrella track.

Once the beginning, middle and end remain synchronized and the dialogue checks match the Umbrella audio, the remux is complete.

The +1001 ms timing approach is a useful detail, especially since both releases are 23.976 fps and can be checked for sync at multiple points throughout the film.
